The clothes that aren’t immediately visible – underwear, socks – are often overlooked in terms of design. Luckily, this isn’t the case with Swedish label <b><a href="http://www.selfridges.com/cat/Happy-Socks/" style="text-decoration: none"><font color="black">Happy Socks</font></a></b>. Every piece is created with a new sense of quality and creative expression. Snug without feeling too tight, these trunks offer a heartwarming fit in stretch-cotton to promote movement. A fitted feel all-over makes this pair a seamless and free-loving underlayer.
